1. A surgical circular fastener apparatus, which comprises:
- an elongated body defining a longitudinal axis and having proximal and distal ends, the elongated body defining a window;
a fastener cartridge disposed adjacent the distal end of the body;
an anvil retainer releasably mounted relative to the fastener cartridge; and
a manually operable release including at least one lock, the manual operable release being accessible through the window and movable between a first position corresponding to a secured condition in which the at least one lock is engaged with the anvil retainer to secure the anvil retainer within the fastener cartridge and a second position in which the at least one lock is disengaged with the anvil retainer to release the anvil retainer from within the fastener cartridge.

13. A surgical circular fastener apparatus, which comprises:
-
an elongated body defining a longitudinal axis and having leading and trailing ends, the elongated body defining a window; a fastener cartridge disposed adjacent the distal end of the elongated body; an anvil retainer releasably mounted relative to the fastener cartridge, the anvil retainer defining at least one lock recess; and an anvil retainer release mechanism for selectively securing and releasing the anvil retainer relative to the fastener cartridge, the anvil retainer release mechanism including; a release housing; a manually operably release accessible through the window, the manually operable release mounted to the retainer housing and configured to move between a first position and a second position; and at least one lock operably coupled to the manually operable release, the at least one lock mounted for movement within the retainer housing between a locked position and an unlocked position upon movement of the manually operable release between respective first and second positions thereof, the at least one lock configured to be received within the at least one lock recess of the anvil retainer to secure the anvil retainer relative to the fastener cartridge when in the locked position, and configured to be released from the at least one lock recess to release the anvil retainer to permit mounting or release of the anvil retainer relative to the fastener cartridge when in the unlocked position. - View Dependent Claims (14, 15, 16)
